Abstract
Description
開口を有する容器と、
前記開口を封止する封止部材と、
前記封止部材に接続され、押圧によって開閉可能に構成された一対の挟持部と、
を備える、ものである。
以下、図面を参照して本発明の実施の形態について説明する。なお各図面においては、各部材を認識可能な大きさとするために縮尺などを適宜変更している。
容器11は、透明であることが望ましく、中空の内部空間11cが視認可能であることが望ましい。内部空間11cは開口11bに連通している。容器11は、例えばガラス製の試験管等であってもよいが、押圧によりたわむ程度の柔らかさの素材により構成することがより好ましい。例えば容器11は、ポリプロピレンやポリエチレン等の合成樹脂により構成されることが好ましい。換言すると容器11は、0.1〜3GPa程度の弾性を有することが望ましい。
上述の構成では、圧力を加えない状態では挟持部13の先端が開いた状態であることを説明したが、圧力を加えない状態では挟持部13の先端が閉じている構成であってもよい。この場合、圧力を加えることにより挟持部13の先端が開くこととなる。この場合であっても、生体組織の把持、搬送、単離をスムーズに行うことができる。
上述した挟持部13の形状はあくまでも一例であり、その他の形状であっても構わない。挟持部13の変形例を図4に示す。当該変形例では、挟持部13aと挟持部13bが支点部材13cによって結合されている。医療従事者は、挟持部13と封止部材12の結合部分付近(例えば図4の矢印部分)を押圧すること及び押圧解放することにより、挟持部13aと挟持部13bの先端を開閉(接離)する。
上述の説明では挟持部13の挟持面131で生体組織を挟んで押圧することを想定したが、容器11に生体組織を押し当てることによって細胞単離を行ってもよい。当該手法を用いる際の構成を図5に示す。
封止部材12には、フィルタが設けられていてもよい。当該構成例を図6及び図7を参照して説明する。図6は、細胞単離器具10の変形例にかかる分解図である。細胞単離器具10は、図1の構成と同様に容器11、封止部材12、及び挟持部13を有する。
